WATER-HEATER,

y all whom t may concern v,

Be it known that,I, ROBERT W. WIEDER- WAX, la citizen of thevUnited States,.residing at Atlantic City, inthe county of. Atlantic and lState ofNew Jersey, have invented certain new and useful Improvements in Water- Heaters, of which the-followingis a. speci-k Y iication.

, This invention relates towater heaters, and more particularly to means for heating the circulating water in Cooling systems of motor vehicles, and it comprises a relatively shallow casing] adapted to be arranged in front of the radiator of a *motorv vehicle, passages communicating with said casing at each side, burner vcasings arranged in said passages, means for permitting introduction of air into said burner casings in a tortuous path, a casing arranged `atthe rear of the radiator and provided with outlets, and means for controlling the passage of gases to said outlets.

In certain makes of automobiles, the clearance between the front of the radiator and the starting crank is very small, and it has been diiiicult to obtain a heating device to be applied to the radiator for heating` the circulating water which wouldV not interfere with the cranking of the engine. If the burners are arranged immediately below the casing, it' is necessary that the casing bie of.

anl appreciable thickness `toiprevent it from burning out.

In the present invention, I have overcome this diiiculty by providing av relatively shallow casing which can be arranged in front of.,v the -radiator of any make of automobiley and still allow suflicient clearance to permit :starting the engine -byv a handcrank.

The burners furnishing heat, are arrangedy Y Sage just above the burner may be made of any desired size, without interfering with the cranking operation and without danger of burning out. The products of combustion when conveyed 'to the relatively shallow Vcasing arranged in front of the radiator are sufiiciently cooled to remove the possibility of burning outv the walls of the casing.

' In the present invention, I have also fprovided means to prevent an undue amount of air from being supplied to the burner which Specification of Letters Patent.

would vcause improper combustion and wouldv cause the burners to smoke.

Where. the products of combustion which heat the circulating air are delivered rearwardly beneath the hood of the motor ve.- h1'cle,. I have foundv that the vfan employed for the purpose of creating a circulation of air through the radiator, draws vthe products of combustion through the outlets at a rapid rate and causes an excessive inflow of air to the` burners. In the present invention, I have provided means for overcoming this dlfliculty by placing a screen within the rear casmg and providing linlets near the bottom ofthe easing whereby the effect of the draft ,created by theY fan is to draw air through the rear casing only.

In the accompanying drawings, I have shown `one rembodiment of the invention. In this showing: v

F'g. 3 is. a horizontal sectional view on line 3 3 of Fig. 2, l1Fig. 4 is a similar `View on line 4 4 of Fig. 5 is a vertical sectional view on line 5 5 of Fig. 2,

, Fig.'v .6 is a similar view on line 6 6 of Fi 1,

is provided with head lamps/1, supported f on a rod or supporting member 5, extending from the frame 6. The usual fenders 7 may be provided.

My improved heater comprises a main casing 8, which is provided with side walls 9 and top and bottom walls 10, whereby a casing is provided open--at the back, and closed at the front and sides. As shown, in Fig. 6 of the drawings, the casing is shallow and extends a very slightdistance in front" of the radiator, whereby itV does not interere with the operation ofthe starting crank (not shown). At each. side .of the casing, a relatively narrow Vcomn-iunicating passage 11 is providedwhich, as shown, extends beyond the sides of the radiator and communi-` cates with a vertical passage 12. The Vertil cal passages which form the combustion chambers and which vare submittedto a; relatively high degree of heat may be made in any desired size and shape', as theyv are so far removed from lthe center of the machine that they will net interfere' with the opera;

" tion of a starting crank.

A- casing' 13, similar iny c'or'istructionl to the casing 8 and-provided' with flanges 14, on four sides, isl arranged at the back of the' radiator.n This casing and the *front casin are maintained in position by means of bolts'A v22. A central opening isprovid'e'd' at the" bottom of the vertical passage 12, andl this central opening is adaptedV to receive a burner frame 23,` the bottom'y of which i'S provided with a flange 24, lslightly spaced from the bottom 21 of the burner casing. The burnerA is'v provided with a wick 25, which extends downwardly in a wi'ck'tube` 26, and projects below the bottom of the burner casing, being ada ted to be inserted in the oil receptacle. uitableregulating,

means 27` are provided for Athe wick. vThe wick tube issurrounded' by' a pair of perforated plates 28 andj29, of the usual-coml struction. Air is admitted to the burner through openings 30,7arranged1y on-.thyel slop'- ing top of theburne'r'casing, and extending, entirely around the burner (see Fig! 3)f 4Within the chamber formed'by the sloping top 22 and the partition v20, there isrovidedy a plurality Vof openings 31 exten ing along two sides. Ay screen132 isA arranged' between'vthe openings'v 30 and 31, the air in passingl through the upper portion of the burner casing being caused t`o` pass through the screen. An air chamberv 33is` provided" between the partitions 19 and" 20, and the partition 19 is provided with two-frow'sfof openings 34", arranged outy of alinement with the openings 31 inthe partition 20. Screens`v 35 are arranged in the chamber" 33 between the: two sets of openings'. When the` air asses int-'o the bottom of the burner casing,

it is `caused to'nd its way"beneaththeffiangey 24-to enter' the burner. i

Assho'wn, the junctioxr ofthe passages 11 andthe vertical passages 12 is rounded on the upperv side, asat 36 (see Fig. 5),. and a curved plateA 37 is arranged onY the lower wall y substantially parallel to the curved portion 36.

, The rear casing 13 is provided-with outlet openings 38. A screen or perforated plate 39 is arranged within this casing between .the openings 38 and the radiator. "A plu# raflity of airinleb openings 40 are provided at any suitable point in the plate, theposition of the openings," being" optional'. openings are disposedto-permit air Vpassing 'into'th'e casing to reach the outletopenings 38, without'` passin'gthroughf thefscree'n 39; p

The; operation ofthe device is as follows: The heater is attached tothe radiator of a motor vehiele by" means of bolts15. rlfhe burnersl are .lighted and the products of combustion pass upwardly through the vertical passagesl 12, the communicating passages 1f, to the'V front* casing 8,- thence througlthe radiator',- heating the circulat ing water'or'otherfluidginto therear casing 13, and through outlet openings 38. The

The"

provision ofthe screenf 39'y prevents" flames" iro'm" the enginev freni'A entering the heater andlcasin'g, and* causing a` tirev in the oil= re- Ceptacles 18. By' provrding1y a curved wall 36V between the passages lla-nd 12', and? the curved plate 37', forming af substantially' parallel wallf on` the opposite side', morey perfeet combustion is obtained as'r-tlie flow of gases and pdltitsi of clbistion isi lSS ob'structed'than' where' square' corners are provided. ir is supplied to theiblurer's throughropenings" 30; screen' 32, openings" 31, screen 35 and openings-"34. The prov1 sion off a' tertuouspassagefor'the introduetion of airfis` advantageous; i`n`1 that,it per-y mits use of the heater while the vehicle is runnifng.-y I means are ot provided for regulatingthe admission ofi air, the-v supply" of air furnished to the burner when'theve'-A hicle` is running is tool great anda Smoky flame resulte which is. disadvantageou's.

The provisionpf inlet4 openings 4e0in1the1 rear? casing', together" thev screen 39, overcomes* a disadvantagelof priorv` constructions', -i-n that, thefope'r'at-in of theffanwhenf the engine isfrunningdr'aws air through theopeninfgslf() and? the opening' 38 without' materially" ali'ectingT the' naturalpaSsage of` the roduc'tsof combustion" through the heater.l

Ile-the absence of' the'i'nlet openingsy 40V and thescreen?v 39,'l theAj fan@ has' a tendency to create' an induced'v dra-ft throughout the heater and causefcirculation atl such a` rapidl rate that, the oilv or other fuelI is .not com# pletely" hurried, resultingin.` the presencev of smoke andi other "u'ndesirablev features.

Itfis to be understoodIJ that` the` form of my inventionherewithshown and' described islfo be takenV asia preferred-example of the same, and that various changes in the shape, relation to the openings in the top'Y of the 55 size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
